POWER DEVICE FOR BALlNG-PRESSES.

SPECIFICATION forming part of Letters Patent Nb. 433,887, dated August 5, 1890.

Application filed .llpril 14., 1890. Serial o. 347,811. (No model.)

To all whom it may concern:

Be it known that we, THOMAS M. CASS and NATHANIEL CAss,citizens of theUnited States, residing at Cameron, in the county of Milam and State of Texas, have invented certain new and useful Improvements in Power Devices for Baling-Presses and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of ref erence marked thereon.

This invention relates to certain new and useful improvements in power devices for balingpresses of that class wherein is employed a disk rigidly fixed to the shaft of the crank and a disk loosely mounted on said shaft; and it has for its object to improve upon prior constructions of this character. We hinge the lugs on the looselymounted disk, and, preferably, place a spring between the said lug and the disk, so that either the weight of the lug or the force of the spring will project or suspend the lug below the surface of the disk.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is an end elevation of the powerframe, the clutch-disks being shown in section. Fig. 2 is a plan of the fixed disk. Fig. 3 is a like view of the loosely-mounted disk with three lugs, and Fig. 4 is a like view of the same with but two lugs.

Like letters of reference indicate like parts in the several views.

Referring now to the details of the drawings by letter, A designates the frame,to which are fixed the boxes B, in which is journaled the crank-shaft C.

D is a pitman or plunger rod operated by V the crank, and to the end (not shown) is de signed to have attached a plunger which presses the hay into the press. (Not shown.) E is a wheel or disk rigidly'fixed to the crank C, and the upper face carries a segmental lug F, arranged inside the periphery and extending for about one quarter of the same. This lug may be integral With or fixedly secured to the disk, as may bepreferred.

G is a wheel or disk loosely mounted on the crank-shaft and upon its inner face recessed, as shown at a, forming a plain rim 1?, and within this recess are pivoted on transverse pins 0 the segmental lugs H, of which there may be two or three, as deemed best. In the drawings are shown both forms. These lugs are pivoted in recesses within the recess of the disk, so that when pressed in their under faces will be flush with the recess a. The pivot ends of the disks are seated in a notch d in the disk, as shown, the outer wall of which forms a guide for the lug in its movement.

I are springs arranged in the recesses in which the lugs are seated, and adapted to press the said lugs outward and yet allow them to yield when necessary.

The power-lever is to be attached to the top of the loosely-mounted disk G.

In operation, force being applied to the power-lever revolvesthe disk G until the segmental lug engages the lug F on the disk E, so that when the upper disk is set in motion the hinged lug engages the lug on the fixed disk and revolves it, forcing the shaft forward, and thus making a stroke. \Vhen the stroke is made, the rebound fromthe hay forces the shaft-disk to revolve faster than the lever to the upper disk travels. As the crank-shaft stops after the rebound, the hanging lug on the upper disk engages the lug on the disk on the crank-shaft and revolves it as before. There is no intermission between the strokes; butthe crank-shaft is continuously in motion, and it makes two strokes to one circle of the lever. This with the twolug disk. WVith the three-lug disk, when the disk is revolved one of the lugs engages the lug on the shaft-disk and the hanging lug immediately in front of the engaged lug is held up in the groove by the lug on the shaft-disk and the lug just behind the engaged lug hangs in position. When the crank-shaft rebounds, it liberates the front lug, before mentioned, and engages the rear lug and at the same time holds up the lug with which it was first engaged, and so on.

What we claim as new is- 1 The combination, with the frame and the crank-shaft journaled therein, of the two disks, one loosely mounted'on the said shaft and recessed and having secondary recesses, and provided with spring-actuated segmental lugs hinged within the secondary recesses, and the other disk fixed on the crank-shaft and having upon its outer face a fixed segmental lug, substantially as and for the pur pose specified.

2. In a baling-press, the combination, with the frame and the crank shaft journaled therein, of two disks, one loosely mounted on R. I. MCCALLA, T. T. HENDERSON.
